How do we determine whether a matrix has an inverse?

WebLet T: V → W be a linear transformation. T is said to be invertible if there is a linear transformation S: W → V such that S(T(x)) = x for all x ∈ V . S is called the inverse of T . In casual terms, S undoes whatever T does to an input x . In fact, under the assumptions at the beginning, T is invertible if and only if T is bijective. WebMany-to-one functions, like y=x^2 are not typically invertible unless we restrict the domain. So if we amend that we only want our outputs to be positive, we can invert y=x^2 to get y=√x. It's just that we will only get positive numbers.
